The following will describe test examples showing that the compounds of the present invention are useful as an active ingredient of insecticides and/or acaricides, where the compounds are designated by the corresponding compound numbers as shown in Tables 1 to 17.

Test Example 1 (Insecticidal activity against tabacco cutworm)

On the bottom of a polyethylene cup of 9 cm in diameter was placed a piece of filter paper having the same size as the bottom size. An emulsifiable concentrate prepared from any one of the test compounds according to Formulation Example 1 was diluted with water into a concentration of 500 ppm, and the dilution (2 ml) was incorporated in an artificial diet for tabacco cutworm (13 g). The artificial diet was placed on the filter paper, and the cup was inoculated with ten 4-instar larvae of tabacco cutworm (Spodoptera litura). After six days, it was examined whether the larvae were still alive or dead, and mortality (%) of the larvae was determined. The results are shown in Table 18.

Test example 2 (Ovicidal and larvicidal activity against diamondback moth)

Several sprouted seeds of radish on the fifth to sixth day after seeding were put into a gauge in which 1- to 3-days adults of diamondback moth (Plutella xylostella) had been left. At the time when 15 to 20 eggs of diamondback moth were laid on each of the sprouted seeds, the test plants were removed from the gauge. An emulsifiable concentrate prepared from any one of the test compounds according to Formulation Example 1 was diluted with water into a concentration of 50 ppm. In the dilution, two sprouted seeds of radish with laid eggs and two sprouted seeds of radish without laid eggs were immersed for 30 seconds, followed by air-drying, and put into a polyethylene cup of 5.5 cm in diameter. After 6 days, mortality of the eggs or larvae hatched from the eggs was determined on the following criteria:

A: 100%;

B: from 90% inclusive to 100% inclusive; and

Test Example 3 (Insecticidal activity against common mosquito)

An emulsifiable concentrate prepared from any one of the test compounds according to Formulation Example 1 was diluted with water. The dilution (0.7 ml) was added to ion-exchanged water (100 ml) to make an active ingredient concentration of 3.5 ppm, which was then inoculated with Twenty final-instar larvae of common mosquito (Culex pipiens pallens). After eight days, the inhibition of eclosion was determined on the following criteria:

A: not less than 90%;

B: from 80% inclusive to 90% exclusive; and

C: less than 80%.

The results are shown in Table 20.

Test Example 4 (Insecticidal activity against southern corn rootworm)

On the bottom of a polyethylene cup of 5.5 cm in diameter was placed a piece of filter paper having the same size as the bottom size. An emulsifiable concentrate prepared from any one of the test compounds according to Formulation Example 1 was diluted with water into a concentration of 50 ppm, and the dilution (1 ml) was dripped on the filter paper. A sprouted seed of corn was put into the cup as a bait. About 30 eggs of southern corn rootworm were also put into the cup, and then sealed. After eight days, it was examined whether larvae hatched from the eggs were still alive or dead, and mortality (%) of the larvae was determined. The results are shown in Table 21.

Test Example 6 (Acaricidal activity against carmine spider mite)

A potted bush bean (Phaseolus vulgaris) of first-leaf stage on the seventh day after seeding was inoculated with ten adults of female carmine spider mite (Tetranychus cinnabarinus) per leaf, and placed in a thermostatic room at 25° C. After six days, an emulsifiable concentrate prepared from any one of the test compounds according to Formulation Example 1 was diluted with water into an active ingredient concentration of 500 ppm. The dilution was sprayed on the potted test plants on a turntable at a volume of 15 ml per pot, and simultaneously injected into the soil at a volume of 2 ml per pot. After eight days, the respective test plants were examined for the degree of damage caused by the spider mites on the following criteria:

-: almost no damage;

+: small damage; and

++: similar damage to that of untreated test plants.

The results are shown in Table 23.

Test Example 7 (Insecticidal activity against Nilaparvata lugens)

On the bottom of a polyethylene cup of 5.5 cm in diameter was placed a piece of filter paper having the same size as the bottom size and ion-exchanged water was dropwise added thereto. An emulsifiable concentrate prepared from any one of the test compounds according to Formulation Example 1 was 200-fold diluted with water into a concentration of 500 ppm, and a stem of rice plant having a length of about 5 cm was immersed in this dilution for 1 minute. After air-drying , the stem of rice plant was put into the cup, which was then inoculated with thirty to forty larvae of brown rice planthopper (Nilaparvata lugens). After six days, it was examined whether the larvae were still alive or dead, and mortality of the larvae was determined on the following criteria:

A: more than 90%;

B: from 80% inclusive to 90% inclusive; and

C: less than 80%.
